To aZZ whom it may concern.-

Be it known that I, MAX F. STADTMULLER, a citizen of the United States,residing at Pomeroy, in the county of Calhoun and State of Iowa, haveinvented certain new and useful Improvements in a Combined Churn andButter-lNorker, of which the following is a specification.

The present invention appertains to mechanism for churning cream in theformation of butter and working the same after the addition of saltthereto, both operations being performed by the same mechanism.

The invention contemplates an apparatus embodying arotary drum and arotary dasher and mechanism for imparting movement thereto, whereby boththe drum and dasher may rotate together, or the drum have movementimparted thereto independently of the dasher, or both be rotatedsimultaneously in opposite directions and at difi'erent rates of s eed.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying drawings, it which Figure 1 is a perspectiveview of a combined churn and butter-worker embodying the invention. Fig.2 is a vertical central longitudinal section of the churn andcooperating parts. Fig. 3 is a transverse section on the line 2!; a; ofFig. 2. Fig. 4 is a detail view of the operating mechanism, showing thegearing moved to cause both the churn and dasher to rotate in oppositedirections. Fig. 5 is a view of the parts shown in Fig. 4, illustratingthe position of the movable gear elements when the churn and dasher arelocked so as to rotate together. Fig. 6 is a detail perspective view ofan end portion of a roller and a supporting-arm therefor.

Corresponding and likeparts are referred to in the following descriptionand indicated in all the views of the drawings by the same referencecharacters.

The framework comprises longitudinal bars 1 and A-standards 2, the legsof said standards being provided near their lower ends with lateralprojections 3, which are apertured to receive the fastenings employedfor connecting the longitudinal bars 1 to the standards. The lower endsof the legs are bent outwardly to provide feet and are apertured toreceive fastenings should it become necessary to secure the framework toa floor or other support. The upper ends of the standards are depressedto receive trunnions at opposite ends of the churn-body, capplates 4being folded or otherwise secured to the upper ends of the standards toretain the trunnions in place thereon, said cap-plates being upwardlydeflected intermediate their ends to fit about the upper portion of thetrunnions. An arch-bar 5 is secured at its ends to projecting endportions of the longitudinal bars 1 and is provided intermediate of itsends with a bearing 6 in which the outer end of the drive-shaft 7obtains a bearing, the inner end portion of said drive-shaft beingsupported in a like bearing 8, applied to the cross-piece of theproximal A-standard2. Motion is imparted to the drive-shaft 7 from anysuitable source of power in any wellknown way, and for this purpose aband-pull 9 is fast to said drive-shaft and is adapted to have powerapplied thereto by means of a drive-belt (not shown) in the accustomedway. The inner end ofthe drive-shaft is provided with a pinion 10, whichis in mesh with the teeth of a cog-ring 11, secured to the end of thechurn body or drum adjacent to the operating mechanism.

The churn body or drum 12 may be of any construction and is preferablycomposed of heads and staves arranged about said heads and held in placeby hoops or bands. Access is had to the interior of the churn. body ordrum through an opening in a side thereof which is closed by means of adoor 13. The

inner wall of the drum is provided with longitudinal strips 14 andangular strips 15. The longitudinal strips 14 terminate a short distancefrom the inner sides of the heads and 'i are spaced apart an equaldistance and have a parallel relation with one another and with the axisof the drum. The strips 15 are arranged in the spaces formed between theheads and the ends of the longitudinal strips 14 and are oppositelyinclined, the purpose being to work the butter from the ends of the,

drum inward toward the center, thereby keeping the same within range ofaction of the rotary churn-dasher.

Trunnions 1-6 and:

2 1, the same obtaining a bearing in an iron 17 are secured to the endsof the drum or 1 churn body and are mounted in the bearings provided atthe upper ends of the standards 2. The trunnion 16 is provided at itsouter end with a packing-gland 18 to make a tight joint between it andthe shaft 1.9 of the retary churn, said shaft passing entirely throughthe drum and having its inner end mounted in an opening formed in thetrunnion 17. The opening in the trunnion 17 receiving the inner end ofthe shaft 19 is closed at its outer endthat is, it does not extendentirely through the trunnion 17. Hence there is no i provision forwaste at this point and no necessity for supplying a packing-gland, asis the case with the trunnion 16.

The dasher is of the rotary type and comprises arms 20, cross-bars 21.,and rollers 22, the latter being journaled between the extremities ofthe arms 20 and longitudinally fluted, so as to effectively work thebutter after the churning operation has been completed. A centralsupport 23 connects the arms 20 at a central point and is formed with alongitudinal opening through which the shaft 19 passes, therebypreventing contact of the cream or butter with said shaft. Each roller22 is provided at its end with a journal 25, which is secured to the endof an arm 20. The irons 25 are let into the arms 20, so to be protectedand prevent contact of the cream or butter th erewith. The dasher is ofa length and width corresponding approximately to the interior length.and diameter of the churn body and drum, so as to thoroughly break upthe butter particles and insure the gathering and the working of thebutter.

.lhe shaft 19 of the rotary dasher pro roots beyond the outer end of thetrunnion 16 and receives a gear-wheel 26, which is splined thereon, butfree to move toward and from the trunnion 16. Clutch-teeth 27 are provided on the inner side of the gear-wheel 26 and are adapted tocooperate with corresponding clutch-teeth 28 at the outer end of thetrunnion 1.6, thereby providing for causing interlocking of the dasherand churn-body, whereby the two may rotate together, as when churning. Apinion 29 is loose upon the drive-shaft 7 and is at all times in meshwith the gear-wheel 26 and moves therewith A half-clutch 30 is providedupon the outer side of the pinion 29 and is adapted to cooperate with ahalf-clutch 31 fast to the driveshaft 7. When the pinion 29 is movedupward to cause its half-clutch 30 to engage with the halfcluteh 31, thepinion and driveshaft 7 rotate together, and by reason of said pinionbeing in mesh with the gear-wheel 26 and the latter in turn splined tothe sh aft 19 of the dasher thelatter will havemotion imparted theretosimultaneously with the churnbody, but in a reverse direction and at a different rate of speed, because of the difference in the diameters ofthe respective cooperating gear elements 26 29 and 10 and 11. Ashipper-lever 32 is pivoted. at 33 to a longitudinal bar of theframework and has positive connec tion with the gear-wheel 26 and pinion29 to cause both to move together upon their respective shafts 7 and 19.

The cream to be churned is introduced into the drum of churn-bodythrough the opening closed by the door 13, and the shipper-lever 32 ismoved to bring the clutch elements 27 and 28 into engagement and theclutch elements 30 and 31 out of engagement, thereby causing the churnand dasher to rotate together. After the cream has been churned and thebutter collected and it is desired to work the butter either toincorporate salt therein or to eliminate milk and water or for anydesired purpose the shipper-lever is moved to throw the gear-wheel 26out of clutched engagement with the churn-body and to throw the clutchmembers 30 and 31 into engagement, and upon continued rotation of theshaft 7 the churn body and dasher are rotated in opposite directions andat different speeds. After the butter has been worked sufficiently it isremoved through the opening closed by the door 13, as will be readilyunderstood.

Having thus described the invention, what is claimed as new is 1. Incombination, a churn-body, a rotary dasher, a drive-shaft, gearingbetween the drive-shaft and churn-body, a gear element splined upon anextension of the dashershaft, a clutch between said element andchurn-body, a second gear element in mesh with the first-mentioned gearelement and splined to the drive-shaft, a clutch between the'second gearelement and the drive-shaft, and means for simultaneously moving thesaid gear elements either to lock the dasher to the churn-body or toimpart opposite rotary movement to said dasher and churn body.

2. In a combined churn and butter worker, the combination of a rotarychurnbody, a rotary dasher mounted in the churnbody and having an endportion of its'shaft extended, a drive-shaft in constant gear with thechurn-body, a gear-wheel splined. to the projecting end. of thedasher-shaft, a clutch between said gearwheel and the churn-body,
